, 2012 We give an introductory account of the AdS/CFT correspondence in the 1/2-BPS sector of ${\cal N}=4$ super Yang-Mills theory.Six of the dimensions of the string theory are emergent in the Yang-Mills theory. In this article we suggest how these dimensions and local physics in these dimensions emerge. The discussion is aimed at non-experts.

On the initial singularity in Kantowski–Sachs spacetime
European Physical Journal C: Particles and Fields, 2021 The emergent universe scenario is a proposal for resolving the Big Bang singularity problem in the standard Friedmann–Lemaitre–Robertson–Walker cosmology. In the context of this scenario, the Universe originates from a nonsingular static state.

On emergent conformal symmetry near the photon ring
Journal of High Energy Physics, 2023 In this note we revisit the emergent conformal symmetry in the near-ring region of warped spacetime. In particular, we propose a novel construction of the emergent near-ring sl(2, ℝ)QNM symmetry.

Emergent Spacetime for Quantum Gravity [PDF]
Everything about Gravity, 2016 We emphasize that noncommutative (NC) spacetime necessarily implies emergent spacetime if spacetime at microscopic scales should be viewed as NC. In order to understand NC spacetime correctly, we need to deactivate the thought patterns that we have installed in our brains and taken for granted for so many years.

Quarks, Hadrons, and Emergent Spacetime [PDF]
Foundations of Science, 2018 It is argued that important information on the emergence of space is hidden at the quark/hadron level. The arguments follow from the acceptance of the conception that space is an attribute of matter. They involve in particular the discussion of possibly relevant mass and distance scales, the generalization of the concept of mass as suggested by the ...

DARK ENERGY AND EMERGENT SPACETIME [PDF]
International Journal of Modern Physics: Conference Series, 2011 A natural geometric framework of noncommutative spacetime is symplectic geometry rather than Riemannian geometry. The Darboux theorem in symplectic geometry then admits a novel form of the equivalence principle such that the electromagnetism in noncommutative spacetime can be regarded as a theory of gravity.

Entropy density of spacetime from the zero point length
Physics Letters B, 2015 It is possible to obtain gravitational field equations in a large class of theories from a thermodynamic variational principle which uses the gravitational heat density Sg associated with null surfaces.

EMERGENT SPACETIME AND THE COSMOLOGICAL CONSTANT [PDF]
International Journal of Modern Physics A, 2008 We address issues on the origin of gravity and the dark energy (or the cosmological constant) from the perspectives of emergent gravity. We discuss how the emergent gravity reveals a noble, radically different picture about the origin of spacetime, which is crucial for a tenable solution of the cosmological constant problem.

Australian Journal of Social Issues, EarlyView.ABSTRACT Nations manufacture non‐belonging of temporary migrants through policy frameworks that produce exclusion. This precarity maximises the economic benefit of temporary migrant labour by minimising their political, social and legal rights. In this paper, we examine how non‐belonging targeting Working Holiday Makers (WHMs) is manufactured in ...

Levels of Spacetime Emergence in Quantum Gravity [PDF]
, 2021 We explore the issue of spacetime emergence in quantum gravity by articulating several levels at which this can be intended. These levels correspond to the reconstruction moves that are needed to recover the classical and continuum notion of space and time, which are progressively lost in a progressively deeper sense in the more fundamental quantum ...
